CAUTION
The direction of travel can be changed without stopping
the machine. But to ensure safety and riding comfort, and
to extend the service life of the power train, do not keep
the machine running at full throttle when changing direc-
tion. Depress decelerator pedal (1) and reduce the engine
speed before changing direction.
1. Depress decelerator pedal (1) to reduce the engine speed.
2. Shift steering, directional and gear shift lever (2) to the
desired position.
REMARK
Check that the backup alarm sounds when joystick is placed in
REVERSE. If the alarm does not sound, please contact your
Komatsu distributor.
When the steering, directional, and gearshift lever is placed in
FORWARD or REVERSE, the machine may deviate slightly to
the left or right, but this is caused by the actuation of the
straight-travel compensation mechanism and does not indicate
any abnormality.
3. Release decelerator pedal (1) and raise the engine speed.
